BRAHMS Data Reconstruction for Dummies!



To do official reconstruction, you need the password for bramreco account.  If you don't know it, ask somebody.
You are going to make ltr, gtr and dst files in order.
All programs related in reconstruction are located in ~bramreco/DataProduction directory.

How to make ltr file

  1. Log on to rcrsuser4 as bramreco from rssh gateway machine.
  2. Go to "DataProduction" directory
  3. Go to an appropriate run directory, eg, run04 for RUN 4
  4. Go to an appropriate specie directory, eg, auau
  5. Go to an appropriate energy directory, eg 200
  6. Go to ltr directory
  7. In this directory, you must have all necessary programs: bratmain script, FileCatalogOption.rb, Jsf.rb, masterReductionCondor.rb, RunInfo.rb, submitLtr.perl and updateScript.sh  (The last two scripts are not necessary, but it will ease your submission process.)  All scripts except bratmain-script are located in ~/DataProduction/scripts/ltr directory.  The easiest and correct way to obtain all scripts is to use updateScript.sh.  For that, just copy updateScript.sh to appropriate working directory.
  8. Edit the content of updateScript.sh to match your option (See set command below). The example is shown below.
  9. Then, run this script to obtain all necessary scripts (all Ruby scripts.)
  10. You also need to copy submitLtr.perl script, If you don't have one, copy from other working directory.
  11. To submit a job, "submitLtr.perl -u username BeginRunNo EndRunNo(optional)"  You are done, get coffee/beer/ or do something else since it will take a while.
  12. To monitor your job (or find status of your job), use crs_status.sh (for simple monitor), or crs_panel (any detail for expert, see the screen capture below.)


How to make gtr file

  1. Log on to rcas machine as a bramreco (It is not necessary to logon to rcrsuser 4)
  2. The follow the step 2-6 from the above ltr instruction
  3. In this directory, you must have all necessary programs: bratmain scripts (you need 2 for gtr), gtr.rb, masterGlobalTracking.rb, submitGtr.perl and updateScript.sh  (The last two scripts are not necessary, but it will ease your submission process.)  All scripts except bratmain-scripts are located in ~/DataProduction/scripts/ltr directory.  The easiest and correct way to obtain all scripts is to use updateScript.sh.  For that, just copy updateScript.sh to appropriate working directory.
  4. Again, edit updateScript.sh accordingly (see the example in ltr)
  5. Once edit updateScript.sh, just run it to obtain all Ruby scripts.
  6. If you don't have submitGtr.perl, just copy from other working directory
  7. To submit a job, "submitGtr.perl -u username BeginRunNo EndRunNo(optional)"  You are done, get coffee/beer/ or do something else since it will take a while.
  8. To monitor, use condor_q or condor_status command.  See man page for any details.

How to make dst file

  1. Log on to rcas machine as a bramreco (It is not necessary to logon to rcrsuser 4)
  2. The follow the step 2-6 from the above ltr instruction
  3. In this directory, you must have all necessary programs: bratmain script, dst.rb, makeDst.rb, submitDst.perl and updateScript.sh  (The last two scripts are not necessary, but it will ease your submission process.)  All scripts except bratmain-script are located in ~/DataProduction/scripts/ltr directory.  The easiest and correct way to obtain all scripts is to use updateScript.sh.  For that, just copy updateScript.sh to appropriate working directory.
  4. Again, edit updateScript.sh accordingly (see the example in ltr)
  5. Once edit updateScript.sh, just run it to obtain all Ruby scripts.
  6. If you don't have submitGtr.perl, just copy from other working directory
  7. To submit a job, "submitDst.perl -u username BeginRunNo EndRunNo(optional)"  You are done, get coffee/beer/ or do something else since it will take a while.
  8. To monitor, use condor_q or condor_status command.  See man page for any details.


Management of disk space

To view the disk space useage

Use "DataFileUsage.perl"



To remove data and associated files from data disks and change status in FileCatalog database

Use "rmdata.rb"
ruby rmdata.rb -b BeginRunNo -e EndRunNo -d dataType(ltr/gtr/dst) -v VersionNo -p ProductionVerNo


To copy data to HPSS for archiving and change status in FileCatalog database

Use "CopyToHpss.rb"

ruby CopyToHpss.rb -b BeginRunNo -e EndRunNo -d dataType(ltr/gtr/dst) -v VersionNo -p ProductionNo
